Specification of Letters Patent.

Patented Dec. 2, 1913.

Application filed December 3, 1912. Serial No. 734,792.

To all whom it may concern: Be it known that I, Or'ro GAMPER, a citizenof the Republic of Switzerland, residing at Zurich, Switzerland, haveinvented new and useful Improvements in Machines for Facilitating thePacking of Magnetic Objects of Oblong Shape; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same, reference being bad to the accompanying drawings,and to letters or figures of reference marked thereon, which form a partof this specification.

In my Patent 1,014,869 of January 16th, 1912, I have described a machinefor facilitating the packin of magnetic objects of oblong shape, in wich machine magnets are arranged at a distance corresponding to thelength of the objects, which magnets have their opposite poles directedtoward each other. The magnets form a groove between them and a feedingdevice causes the objects to pass between the magnet poles and while theobjects are being placed parallel by the magnetic attraction of thepoles, they are moved forward by the carrier. The objects placedparallel in this manner during the moving may beremoved by hand from thefeeding device and packed in boxes. This can only easily be done whenthe objects are of such length that they can be seized by the wholehand. For short objects where the magnetic poles are arranged at only asmall distance from each other, so that one cannot get in'by the wholehand but only by one or two fingers, this device is not so handy. Inthis case the filling of the short objects in a packing receptacle wouldbe difficult. There as also beenrproposed a device in which there isprovi ed a vertical groove which is closed at four sides. In this devicethe direction of filling coincides of course with the longitudinaldirection of the groove. Because the fillin opening has only a smallcross-section this machine works only very slowly. The vertical grooverenders a control impossible and causes obstruction.

By the device according to this invention these drawbacks are overcomethereby, that a horizontal stationary groove or canal is formed betweenunlike poles of a stationary magnet the feeding being performed at thesame time on the whole length of the groove and the emptying of thegroove being performed transverse to the direction of filling 111 apacking receptacle after. the compression of the objects in the groove.

In the drawings an example of the machine fcrming the subject matter ofthis invention is shown.

Figure 1 is a side elevation of the same partly in section. Fig. 2 is avertical section on line 11-43 of Fig. 1. .Fig. 3 is a plan view of thesame. Figs. 4 and 5 are detail views.

A shaft 21 which is impelled by a motor not shown in the drawingcontinually rotates and therewith rotates an eccentric 16, on whichthere rests by means of yielding plates 11 a rocking plate 14 which isarranged at the front side of a receptacle 15. The plates 11 areyieldingly mounted on oscillating bars 12 and 13 so that the wholereceptacle 15 can rock therewith. Below the front side of the rockingplate 14 a roove or canal is formed by two feedin p ates 4 and 5 ofnon-magnetic material, t e plate 4 being secured to the leg 1 and theplate 5 to the leg 3 of a horse-shoe magnet. The magnet is excited by amagnet coil 18. The leg 3 is movable on a support 2 by means of a. screw7 so that the distance of both legs can be adjusted. Between both legs 1and 3 a shallow trough 6 is mounted to turn about a hinge 22 and may beexchanged. A beater 19 is mounted to turn about the same hinge in thedirection of the arrow (Fig. 1) and the beater is held in verticaldirection by a sprin 19". The trough 6 rests on a strong spring 6? andis held by it in horizontal position between the legs 1 and 3 of thehorseshoe magnet. A foot lever 8 o crates first-1y a switch 9 insertedinthe circuit of the magnet eoil 18, which switch is opened by moving thefoot lever downward, and secondly a pusher rod 10 which is raised bymoving the foot-lever downward, whereby the rocking plate is lifted fromthe eccentric 16, so that the feeding is stopped. At the same time aplate 17 is raised, which is arranged above, thefeeding plate. By thismeans the )late 17 is moved in the path of the objects in ling down fromthe rocking plate.

The machine operates as follows: If the foot lever is in its upperposition the switch 9 is cut in and the horse-shoe magnet is excited, sothat there is a stron magnetic field between the legs 1 and 3. Therocking plate 14 is rocked by the eccentric 16, so

that nails in the receptacle 15 slide on the rocking plate. and singly"fall between the feeding plates 4;, 5, where they move in the magneticfield so that by moving farther down they move parallel into the trough6. After the trough is filled and the roove between the feeding platespartly fille with loose parallel nails the foot lever is moved downward,the switch 9 is opened and the exciting of the horse-shoe magnet isstopped and the nails in the groove will sink into the trough. At thesame time the rocking plate 14 is lifted from the eccentric 16 so thatthe feeding is stopped and the plate 17 is turned in the path of thenails falling in the groove, so that they are prevented from movingfarther downward. Then the beater 19 is moved downward against the forceof the spring in the direction of the arrow (Fig. 1) and the nails areclosely pressed thereby. cated in dotted lines, Fig. 1 is moved onto thefree end of the trough 6, the latter is moved downward and the nailsplaced parallel are suddenly delivered in the packing box which iswholly moved on the trough. After the trough is emptied it movesautomatically upward between the legs of the magnets and is read for useagain. In this manner it is possi ].e to place the smallest magnetic objects of oblong shape parallel and to fill them in packages.

Since the objects can. be seen while they are placed parallel, theobjects which would cause trouble in other devices, (for example wasteof wire, nails which are longer than those to be packed, and the like)can be re moved by hand without stopping the feedmg.

By a machine according to this invention there may also be separatednails of difl'er-.

ent lengths by correspondingly cons ructing the groove between the twolegs of the magnet. For separating nails of two different lengths thedescribed machine may be used without any change, by adjusting thegroove Hereafter a packing box 20 indi-- to the length of the shortnails. I'he long nails remain on the mouth, where they may be removed byhand. f

I claim:

1. In a device for facilitating the packing of slender magnetic objectsof oblong shape, a horse-shoe electro-magnet, a canal of U- shapedcross-section arranged between the legs of the electro-magnet, andfeeding means arranged abovethe open longitudinal side-of said canaladapted to distribute the objects to be packed over the whole length ofsaid canal.

2. In a device for facilitating the packing of slender magnetic objectsof oblong shape,

a horse-shoe electro-magnet, the legs of said magnet being adjustable todifferent distances from each other and forming a horizontally arrangedgroove, a hinged bottom member provided with a free end adapted toreceive a packing box, and feeding means arranged above the openlongitudinal side of said groove adapted to distribute simultaneouslythe objects to be packed over the whole length of said groove.

3. In a device for facilitating the packing of slender magnetic objectsof oblong shape, a horse-shoe electro-magnet forming a horizontallyarranged groove, a shallow trough hinged below the groove provided Witha free'end adapted to receive a packing box,

into which the -trough is emptied in the transverse direction of thefeed, feeding means arranged above-the open longitudinal side of saidgroove adapted to distribute simultaneously the objects over the wholelength of said groove, and a device adapted to interrupt the currentexciting the magnet and stop the feeding simultaneously.

In testimony that I claim the foregoing as my invention, I have signedmy name in presence of two subscribing witnesses.
